Adam Gase will become a good NFL head coach. I’ve consistently said that, and I stand by it.

Problem is, South Florida and the Miami Dolphins didn’t have the patience to wait for the 40-year-old coach to mature and learn from his mistakes.

He had plenty of missteps during his three-year tenure with the Dolphins that produced a 23-25 record before he was fired last week. But it was no surprise that Gase landed on his feet with another NFL franchise so quickly.

Allow us to play a game of fact or fiction regarding Gase’s tenure with the Dolphins, which is being subjected to revisionist history now that he’s been tabbed as the next coach of the rival New York Jets.

Is Gase a good leader? This is a fact.

His confidence, charisma and relatability leads me to say yes. Players want to play for coaches such as Gase because their personality helps them win over the locker room.

Problem is, when you’re cocky, and Gase is indeed that, sometimes it rubs people the wrong way. Personalities clash, and that happened a lot in Miami with stars such as Jarvis Landry, Ndamukong Suh, Kenyan Drake, Mike Pouncey and Jay Ajayi, and it cost the Dolphins plenty of the organization’s top talent.

Is Gase’s reputation as an offensive guru and quarterback whisperer valid? That’s fiction. He gained that reputation after riding the coattails of Peyton Manning in Denver.

Gase is smart and creative. But he’s too reliant on the passing game, and he doesn’t adjust very well to what opposing defenses are doing. The Dolphins finished 31st on offense last season, and that was the lowest ranking in franchise history. Miami ranked 26th in scoring and had the 29th-ranked defense, which Gase take a hands-off approach to (so the Jets better have a good defensive coordinator).

Anyway, here are some of the musings from around the web, other teams’ supporters...

Miami consistently struggled on third downs throughout Gase’s tenure. The Dolphins’ offense, which was outgained by 1,619 yards last season, consistently started games slowly all three seasons under Gase.

Ryan Tannehill’s passer rating improved slightly with Gase, but plenty of that was smoke and mirrors because of all the goal-line passes thrown and the hand-offs that counted as passes, which were a staple of his offense. Tannehill threw 87 touchdowns and 54 interceptions before Gase, and 36 and 21, respectively, with him as the play-caller in 24 games together. That slight uptick does not validate the reputation of a quarterback whisperer.

Does Gase run a disciplined franchise? Definitely fiction.

In 2017, Gase infamously said he had two rules: “Do your job and be on time.” Do you need more evidence that he runs a loose ship? When you’ve got good leadership, being a player’s coach works, but the Dolphins didn’t have good leadership.

The Dolphins were one of the most penalized teams in two of his three seasons. And Miami had numerous off-the-field incidents, including offensive line coach Chris Foerster being fired after a viral video of him snorting a white powdery substance in his office hit the web, linebacker Lawrence Timmons going AWOL the night before the 2017 season opener, linebacker Rey Maualuga being arrested the night before a game in 2017 and safety Reshad Jones refusing to go back into a game — all of which raised red flags about the team’s culture.

While Gase knows how he wants to build a team, the execution was consistently flawed from day one. Most of the moves Gase advocated for didn’t work, with Albert Wilson and Frank Gore being among the few exceptions. The Dolphins spent a ton of resources overpaying average players in 2017 because Gase wanted to keep the core of his 2016 playoff team together. That strategy blew up in Miami’s face, as did the signing of quarterback Jay Cutler for $10 million, which everyone in the organization had to be talked into by Gase. Trading for tight end Julius Thomas was a colossal disaster. Gase’s latest purge, which was in the name of creating a better “culture,” led to the signing of half a dozen aging players. Of that veteran group, Danny Amendola was the only player who didn’t finish the year on injured reserve.

Did Gase lose the Dolphins locker room? This is a stone-cold fact.

Gase has the smartest-guy-in-the-room syndrome, and that gets old quick. Buying in to a philosophy requires the team believing in the coach selling the goods. Players stopped believing in Gase and his coaching staff after the Minnesota game, when numerous players claimed coaches did a poor job preparing the team for what the Vikings were doing offensively and defensively. That was the start of Miami’s three-game losing streak that followed the Miami Miracle, and sealed his fate.

Gang Green came to an agreement with the former Dolphins head coach Wednesday...

Gase’s loyalty to and excuse-making for Tannehill led to many players checking out, and wanting out. Numerous prominent players wanted no part of the organization if both returned, and hinted the team would go through the motions just like they did when Joe Philbin returned in 2015.

While Gase continues to have supporters inside the organization, a large population of the team felt his tenure had run its course, which is why the change was made.

Jets fans had better hope Gase has learned from his mistakes in Miami because if he hasn’t, history will definitely repeat itself.
